*4 Claims. (c1. 167-88) The invention relates to improvements in hair rinsin preparations adapted for use for such purpose on human hair and has for its primary object the provision of an improved preparation of 5 the character indicated which will preserve the textureof the hair in its natural fineness and,

luster.

Other objects will appear hereinafter.

The invention consists in the preparation hereinafter described and claimed. I f

In making up the preparation phthalic acid and potassium acid phthalate are mixed together in various proportions and in some instances, furoic acid added thereto. The phthalic acid used is chemically known as either ortho-phthalic or benzene di-carboxylic aci d. The potassiumv acid phthalate employed is knbwn chemically as such and may be more definitely described as the mono Potassium salt of the (ii-basic acid. The furoic Y acid employed is known chemically as pyromucic sold or furan-carboxylic acid. 1f desired, either direct or acid coal tar colors, including certain of the certified food colors, may be blended to get the correct shade, and an acid dye asistant such aluminum lactatemay be incorporated.

Desirableproportions and methods of mixing are as follows: I I

450 grams phthalic acid, 45 grams potassium thoroughly mixed together in a mechanical mixer and sifter, approximately one gram of this com-'- position, which is colorless, maybe used as a single 725 gramsiphthalic acid, 20 grams potassium acid phthalate,1'l5 grams furoic acid, 50 grams aluminum lactate and 30 grams of Tartrazine are.

used and mixed thoroughly in a mechanical mixer and sifter, Approximately one'gram, of this solution may be used as a single color rinse.

1145 grams furoic acid, 260 grams phthalic acid, 15' grams potassium acid phthalate. 50 grams aluminum lactate and 30 grams Tartrazine are thoroughlymixed together in a mechanical mixer and sifter. Approximately one and one-half color rinse,

. 1410 grams potassium acid phthalate, '50 grams valuminum lactate, 25 grams Sunset Yellow RC1",

acid phthalate and 505 grams furoic acid'imay be grams-of this composition are used as a single acid, 50 grams lactate, 25 grams Sunset Yellow PCB, 10 grainsv .oughly mixed ina mechanical mixer and sitter.

10 grams Ponceau SK and 5 grams Indigotine are mixed thoroughly in a mechanical mixer and sifter. Approximately one and one-half grams of this composition are used as a single color rinse.

.1425 grams furoic acid, 50 grams aluminum -ii lactate and grams Indigotine are mixed thoroughly in a mechanical mixer and siften. Ap-

proximately one and one-half grams of this composition are used as a single color rinse. r

The phthalic acid, potassium acid phthalate,,l

.and furoic acid employed leave the hair soft and pliable and do not render the same harsh and brittle after a time as do such acids as tartaric and citric acids. This is particularly true when the phthalic acid and "potassium acid phthalate 15 are used together. The acid dyes Tartrazlne,

' Sunset Yellow, Ponceau, and Indigotine are all water soluble acid coal tar coloring substances and will'be found to be highly eillcacious for the purpose.- r j Preferably the composition is mixed in the powder form and packaged for-,resale as such. However, the preparation may be put up in tablet, cake, paste or concentrated solution, as desired.

The requisite quantity. of the composition should be dissolved in-approximately. one quart of warm water and the hair rinsed in the usual manner. either with or without previously shampooing the The ingredients employed are not deliquescent I curds from thehair and will preserve the textiire of the hair in its natural fineness and luster.

While I have set forth the preferred embodiments of my invention, these are capableof varla-' tion and modification without departing from the spirit of the invention. Therefore, I do not wish to be limited to theprecise detailsdisclosed, but desire to availmyself of such variations and modifications as fall within the scope of theappended claims.

I claim: 11A hair rinse including phthalic acid.

2. A-hair rinse including potassium a oidphthalate. f.

including fum c acid,

4. Ahairrmseincludingoneofthegrmrpeom r *sisting ofphthalic acid: acid phthalate;' fur oic acid; and water H colo matter.
